Description |
|
Select Measurement Objects |
Click this button to select existing measurement objects on an image. You can edit and delete selected measurement objects or save them in a parameter set. The standard MS-Windows conventions for multiple selection apply for the selection of objects. |
|
Load Measurements and ROIs Save Measurements and ROIs |
You can save measurements and ROIs in a parameter set and load them on a different image. |
|
Click this button to redefine the origin of the coordinate system for the active image. |
|
|
Use this measurement function to define the exact position of individual pixels. |
|
|
Use these measurement function to measure the linear distance between two points on an image. |
|
|
Perpendicular Line |
Use this measurement function to measure the distance between a measurement point and an axis on an image. You first define the axis, then the measurement point. |
|
Circle to Circle |
Use these measurement function to measure the distance between two circles. Define both circles by three points on the circle perimeter. The distance between then centers of the two circles is measured. |
|
Polyline Freehand Polyline |
Use these measurement function to measure the linear distance between two points on an image. You can either determine the course of the line through single control points or you can draw the line with the left mouse button pressed. Click the right mouse button to finish the definition of a line. |
|
Use these measurement function to measure an angle on an image. If you want to measure the length of the legs in addition to the angle, use the Angle Ruler measurement function. |
|
|
Use these measurement function to measure the area and perimeter of a rectangle on an image. |
|
|
Use these measurement function to measure the area and perimeter of a circle or an ellipse on an image. You can either define the circle using 2 points on the perimeter of the circle (3 Point Circle) or by using the center and the radius (2 Point Circle). |
|
|
Closed Polygon Interpolated Polygon Freehand Polygon |
Use these measurement functions to measure the area and the perimeter of an arbitrarily formed two dimensional image object. You define the individual points on the edge of the object. Rightclick to finish the measurement. Using the Freehand Polygon measurement function, you can draw the object while keeping the left mouse button depressed. |
|
Use the magic wand to measure the area and the perimeter of an arbitrarily formed two dimensional image object. |
|
|
Click this this button to snap a measurement object to the nearest brightest or darkest pixel. |
|
|
Click this button to determine the image's center of symmetry. |
|
|
Click this button to delete all measurement objects that are currently selected on the image. |
|
|
Click this button to export the measured values to an MS-Excel sheet or to a text file. |
|
|
Click this button to select the measurement parameters that are to be displayed in the results sheet. |
|
|
Click this button to specify settings for the interactive measurements. |
